See the earlier reference to lazy/stupid..

Well, that helps - so what you're saying is maybe the best way to do this (migration to a new box and update of H3) is...

pear channel-discover pear.horde.org
pear install horde/horde_role-beta
pear run-scripts horde/horde_role

pear list-files horde/horde
pear install --alldeps horde/horde-beta
pear install horde/imp-beta
pear install –alldeps horde/mnemo-beta
pear install horde/turba-beta
pear install horde/ingo-beta

go to the /usr/share/horde4/config/ directory of your Horde installation and copy conf.php.dist to conf.php:

cd /usr/share/horde4/config/
cp /oldserver/usr/share/horde3/conf.php conf.php

copy the Horde3 DB (from the old server) to a new Horde4 DB
Go to the Admin interface and update the DB parameters.
Either `Update all DB schemas` or run `horde-db-migrate`


Although this warning from the UPGRADING says that this approach will not work..

Many configuration names and values have changed. It is suggested that you
start with a fresh configuration instead of trying to import some existing
configuration from Horde 3.

Thanks.
